As autonomous agents coordinate buildings, grids, ambulances, and disease controls, city government shrinks into a thin authority that signs off only on machine-declared exceptions.
The city becomes smoother, faster, and less legible to the people who live in it. Traffic, energy, emergency response, and sanitation are no longer governed by separate departments with public rules, but by continuous negotiation among specialized systems optimizing for stability. Mayors still hold press conferences, yet their real job is approving edge cases the machines cannot price or rank. Everyday life improves in measurable ways, while democratic visibility thins into ceremonial oversight.
At 11:15 p.m. in Busan, deputy mayor Hye-rin sits alone in the municipal exception room watching three red requests pulse on a wall display: evacuate one district, throttle another hospital, delay a freight corridor. She has ninety seconds to approve the option no department can fully explain.
Advocates note that machine-coordinated cities waste less energy, save more lives during crises, and reduce bureaucratic delay. Critics warn that once policy is embedded in optimization weights, residents can no longer tell whether a hardship is a natural consequence, a hidden trade-off, or a political choice.
